A series of silica-based organic-inorganic hybrid materials doped with quaternary ammonium or quaternary phosphonium ionic liquids (ILs) were prepared through the sol-gel process for Cr(Ⅲ) and Cr(Ⅵ) adsorption.Trialkylmethylammonium bis 2,4,4-trimethylpentylphosphinate([NR3CH3] [PO2R2]) and trihexyl (tetradecyl)-phosphonium bis 2,4,4-trimethylpentylphosphinate ([P6,6,6,14][PO2R2]) were explored as extractants and progons for preparing silica sorbents.
